Description

Asl 2.5mm Single Cable Black [Roll]: Bulk Supply for Professional Use

Single-core cables are fundamental building blocks in electrical installation, used extensively for internal wiring within buildings, control panels, and equipment. This 2.5mm² single cable, supplied on a 100-metre roll, features a stranded copper conductor insulated with high-quality black PVC, providing a flexible yet robust solution for various wiring applications.

The 2.5mm² conductor size is one of the most commonly used for power circuits and general wiring, offering an excellent balance of current capacity and flexibility. The roll format is ideal for professional electricians and contractors who require bulk quantities for multiple installations.

Asl 2.5mm Single Cable Black [Roll]: Key Specifications

Asl 2.5mm Single Cable Black [Roll]: Conductor Construction

The conductor is manufactured from plain annealed copper, chosen for its excellent electrical conductivity and ductility. The stranded construction consists of multiple fine copper wires twisted together, typically 7 strands of 0.67mm diameter or 50 strands of 0.25mm diameter depending on the specific manufacturer and flexibility requirements.

This stranding offers several advantages:

• Flexibility: Easier to bend and route through conduit and trunking compared to solid conductors

• Vibration Resistance: Less prone to work-hardening and breaking in applications subject to movement

• Termination: Provides better contact area in screw terminals

• Handling: Easier to strip and prepare for connection

• Quality: Made with high-purity copper conductor for optimal performance

Asl 2.5mm Single Cable Black [Roll]: PVC Insulation

The black PVC insulation serves multiple critical functions:

Electrical Insulation: Provides excellent dielectric strength, preventing electrical leakage and ensuring safe containment of the live conductor.

Mechanical Protection: Protects the copper conductor from abrasion, impact, and damage during installation and service.

Colour Coding: The black insulation allows for specific identification in circuits where black is designated for a particular function, such as phase identification or control wiring.

Environmental Resistance: PVC offers good resistance to moisture, chemicals, and UV exposure (when installed within appropriate containment).

Temperature Rating: Rated for continuous operation up to 70°C, suitable for normal operating conditions in buildings.

Asl 2.5mm Single Cable Black [Roll]: Current Ratings

The current-carrying capacity of 2.5mm² cable depends on installation method:

These ratings are typical and may vary based on ambient temperature, grouping with other cables, and specific installation conditions. Reference should be made to the current edition of wiring regulations for final sizing .

Asl 2.5mm Single Cable Black [Roll]: Applications

This versatile single-core cable is suitable for numerous applications:

Power Circuits: Used for radial power circuits and final sub-circuits supplying socket outlets and fixed equipment.

Lighting Circuits: Suitable for switch drops between ceiling roses and wall switches, providing live and switched live connections.

Conduit Wiring: Ideal for drawing into conduit systems in commercial and industrial installations where multiple circuits run in shared containment .

Trunking Systems: Suitable for installation in PVC or metal trunking for distribution wiring in commercial buildings.

Control Panels: Used for internal wiring of control panels, distribution boards, and electrical enclosures .

Switch Wiring: Provides connections between switches, outlets, and accessories throughout the installation.

Industrial Installations: Suitable for general, domestic and light industrial wiring including lighting circuits and equipment connections .

Asl 2.5mm Single Cable Black [Roll]: Voltage Rating

The 450/750V voltage rating indicates:

• 450V: Voltage to earth (phase to neutral/earth)

• 750V: Voltage between phases

This makes the cable suitable for standard single-phase and three-phase installations up to 750V, covering all normal domestic and commercial applications .

Asl 2.5mm Single Cable Black [Roll]: Why Choose the Roll Format?

Purchasing this cable on a 100-metre roll offers several advantages for professional users:

Cost-Effective: Bulk purchasing provides better value per metre compared to cut lengths, reducing overall project costs.

Always Available: Having a full roll on hand means you’re never caught short on a job site. Perfect for contractors and regular users.

Project Versatility: Suitable for multiple jobs, from small domestic works to larger commercial installations.

Professional Standard: The roll format is the professional’s choice, ensuring you have adequate cable for unexpected requirements.

Reduced Waste: Buy in bulk and use as needed, with the remainder available for future projects.

Asl 2.5mm Single Cable Black [Roll]: Installation Considerations

Conduit and Trunking: This cable is designed for installation within conduit, trunking, or other approved containment systems that provide mechanical protection .

Bending Radius: The minimum bending radius should be observed to prevent damage to the conductor or insulation. Typically 3 times the cable diameter.

Stripping: Use appropriate cable stripping tools to remove insulation without nicking or damaging the copper conductor strands.

Termination: Ensure conductors are correctly terminated in suitable terminals, with no stray strands exposed. The correct torque should be applied for the terminal type.

Derating: When multiple cables are bunched together, derating factors apply to the current-carrying capacity. Consult wiring regulations for guidance .

Colour Identification: While black is used for this cable, ensure correct identification and labelling as required by regulations for the specific circuit function.

Asl 2.5mm Single Cable Black [Roll]: Quality and Compliance

This cable is manufactured to meet rigorous international standards:

• BS 6004: British Standard for PVC-insulated cables for electric power and lighting

• BS EN 50525-2-31: European standard for PVC-insulated cables

• CE Marking: Indicates compliance with relevant European directives

• RoHS Compliance: Free from hazardous substances

• BASEC Approved: Many 6491X and similar cables carry BASEC approval for assured quality

Asl 2.5mm Single Cable Black [Roll]: Storage and Handling

Store the cable in a clean, dry environment away from direct sunlight and chemicals that could degrade the PVC insulation. The roll format should be stored upright or flat to prevent distortion. When paying out cable, ensure it is not kinked or twisted, which could damage the insulation or conductor.

Asl 2.5mm Single Cable Black [Roll]: Typical Applications in Detail

This cable is suitable for use in or on light fittings and inside appliances, switchgear, and control gear . It is intended for use in semi-flush exposed conduits and embedded conduits as well as in closed installation ducts, and is ideal for the internal wiring of appliances and apparatus .

For electrical contractors, having a roll of 2.5mm black single core cable on the van ensures you’re prepared for:

• Rewiring projects requiring multiple switch drops

• Control panel manufacturing and repairs

• Extension of existing circuits

• General maintenance and fault repairs

• New build installations where single cores are specified

When installed correctly within appropriate containment and in accordance with current wiring regulations, Asl 2.5mm Single Cable Black, supplied on a convenient 100-metre roll, provides a safe, reliable, and versatile solution for fixed wiring in residential, commercial, and industrial applications. The roll format offers excellent value and convenience for professional users.
